| Module Overview |
| Complex analysis, traditionally known as the theory of functions of a complex variable, is one of the fundaments of modern mathematics and used in many branches of mathematics and physics. In this module the main results of this theory are presented. |
|
|
| Prerequisites/Co-requisites |
| CALCULUS MAT1015 |
|
|
| Module Aims |
| This module introduces students to the theory of functions of a complex variable. |
|
|
| Learning Outcomes |
At the end of the module the student should have a thorough understanding of the theory of complex functions of a complex variable and should be able to apply this knowledge in a variety of contexts. In particular the student should be able to:
* Understand what complex differentiation is
* Quote, derive and apply the Cauchy-Riemann equations
* Study convergence properties of a complex power series
* Perform contour integrations of continuous functions
* Understand and apply Cauchy's theorem and Cauchy's formula
* Derive analyticity and Liouville's theorem from Cauchy's formula
* Apply Taylor's and Laurent's theorems to obtain power series expansions
* Identify and classify singularities of complex functions and find residues of simple
poles
* Derive and apply the residue theorem to compute real integrals using residue calculus
